Chapter 4 Optical Loss Budgets

Optical Loss for 8-Port Multi-Service Muxponders

In both the receive and transmit directions, splitter 8-port multi-service muxponders attenuate the ITU

signal significantly more than the nonsplitter transponder line cards.

Table 4-3 shows the optical loss for the splitter and nonsplitter 8-port multi-service muxponders

supported by the Cisco ONS 15530 in the transmit and receive directions.

Optical Loss for 2.5-Gbps ITU Trunk Cards

In both the transmit and receive directions, splitter 2.5-Gbps ITU trunk cards attenuate the ITU signal

significantly more than the nonsplitter 2.5-Gbps ITU trunk cards.

Table 4-4 shows the optical loss for the splitter and nonsplitter 2.5-Gbps ITU trunk cards supported by

the Cisco ONS 15530 in the transmit and receive directions.
